In today's highly competitive industrial valve market, the bronze butterfly valves manufactured by J-VALVES in China stand out and attract much attention. What unique aspects enable them to demonstrate strong market competitiveness among numerous valve products? Let's explore this in depth.

In the industrial field, ANSI 150LB bronze butterfly valves are widely used. Dimensional tolerances and fluid compatibility in its design specifications are two key aspects, which will be analyzed in detail below.

I. Introduction
In the industrial field, bronze butterfly valves are widely used, and their leakage rate is one of the key indicators for measuring the performance of valves. Different international standards have their own regulations for the leakage rate testing of butterfly valves. Among them, API 598 and ISO 5208 are two commonly used standards. Understanding the differences in their pressure curves helps to evaluate the quality and performance of bronze butterfly valves more accurately. This article will conduct a comparative analysis on this aspect.
